Evaluating only first HTTP request in HTTP 1.1

I need to evaluate only first request in HTTP 1.1 packet and than select the appropriate pool. When I use HTTP_REQUEST, the rule evaluates every HTTP request it sees in HTTP 1.1 packet and then choose...
application delivery
dev

Assuming that there are several requests in a single Keep-Alive connection (rather than in a single packet), you could disable the HTTP_REQUEST event after the first request is seen, then that pool will be used for the life of the connection:

when HTTP_REQUEST {
  if { [HTTP::uri] contains ".gif"} {
    pool servers2
  } else {
    pool servers1
  }
  event disable
}

(Should have thought of that yesterday, I guess -- sorry!)
